Hi limel,
If you do not get a response from someone who was purchased the display from another seller with better software, perhaps you should consider writing a new sketch. Experts on this forum will help if you show that you are willing to learn and do not ask for someone else to write the sketch for you.
The sketch you have been given is useful as a demonstration for how to drive the display, but not very useful for your application.
Here are my suggestions:
- Consider the display as 2 lines of 16 characters. Plan how you would want to display time, date etc. on this grid
- Consider what characters you will need: "0".."9" "/" "c" "%" etc.
- Consider using the SPI pins on the Arduino and the SPI library for best performance
- Consider using the timer2 library for refreshing the display, so that your main loop() code can use libraries to read the time, temp, humidity etc and use delay() while the display continues to be refreshed without flickering.
I hope these suggestions give you some ideas.
Paul
